예시

다음은 완전히 자급자족하는 독립적인 작업 흐름(workflow)입니다.

-- do this if you don't have a topology setup already
-- Creates topology not allowing any tolerance
SELECT TopoElement(topo)
FROM neighborhoods;

-- using as cast
SELECT topology.TopoElementArray_Agg(topo::topoelement)
FROM neighborhoods
GROUP BY city;

TopoElementArray_Agg, TopoGeometry, TopoElement
